what are fibre optics

Fiber Optics is the technology in which communication signals in the form of modulated light beams are transmitted over a glass fiber transmission medium.

Fiber optic technology offers high bandwidth, small space needs and protection from electromagnetic interference, eavesdropping and radioactivity.

Fiber optic technology makes use of light to carry digital signals via optical cables. Fiber optic cables are very thin glass wires made from extremely pure optical glass.

This technology is based on the concept of light reflection. In the case of fiber optics technology, light carrying digital signals is reflected inside the optical cable to transfer information.

Total internal reflection is the principle behind the success of this technology.

fibre optics is A technology that uses glass (or plastic) threads (fibers) to transmit data. A fiber optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.
Fiber optics has several advantages over traditional metal communications lines:

Fiber optic cables have a much greater bandwidth than metal cables. This means that they can carry more data.
Fiber optic cables are less susceptible than metal cables to interference.
Fiber optic cables are much thinner and lighter than metal wires.
Data can be transmitted digitally (the natural form for computer data) rather than analogically.
The main disadvantage of fiber optics is that the cables are expensive to install. In addition, they are more fragile than wire and are difficult to splice.

Fiber optics is a particularly popular technology for local-area networks. In addition, telephone companies are steadily replacing traditional telephone lines with fiber optic cables. In the future, almost all communications will employ fiber optics
